Upgrading DRAM
This section describes how to upgrade dynamic random-access memory (DRAM) on the system board.
You might need to upgrade DRAM for the following reasons:
•
You have upgraded to a new Cisco IOS software feature set or release.
•
You are using very large routing tables or many protocols (for example, when the router is set up as
part of both a large external network and your internal network).

OL-5474-01
Upgrading DRAM
To see how much memory is currently installed in the router, enter the show version command. Near the
middle of the resulting output, a message similar to the following appears:
Cisco 2610(MPC860) processor (revision 0x200) with 28672K/4096K bytes of memory.
This line shows how much memory is installed (in this example, 28672Kb / 4096 Kb). The first number
represents primary memory and the second number represents shared memory.
Memory Capacities
Cisco 2600 series routers use two types of dynamic memory:
Caution
•
5-V EDO DRAM DIMMs (Cisco 2610, Cisco 2611, Cisco 2612, Cisco 2613, Cisco 2620, and
Cisco 2621 routers)
•
3.3-V SDRAM DIMMs (Cisco 26xxXM, Cisco 2650, Cisco 2651, and Cisco 2691 routers)
EDO DRAM and SDRAM DIMMs are not interchangeable. Although it is mechanically possible to
install an incorrect DRAM DIMM into a router, the router does not boot.

Upgrading DRAM
Procedure for Cisco 261x, Cisco 262x, Cisco 265x, and Cisco 26xxXM
Most Cisco 2600 series routers contain two 100-pin dual in-line memory module (DIMM) sockets (or
banks) for DRAM. (See Figure 5.) Each socket can be filled with a 100-pin DRAM DIMM (EDO or
SDRAM DIMMs, depending on router model). You can use the memory-size iomem software command
to configure DRAM as a mixture of shared memory, which is used for data transmitted or received by
network modules and WAN interface cards, and primary or main memory, which is reserved for the CPU.
For further information about this command, refer to the Cisco IOS Release 12.3 configuration guides
and command references, located at the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/index.htm
Caution
It is critical that the correct voltage DRAM modules be installed in Cisco 2600 series routers. Using
the incorrect memory causes the system to malfunction and may cause damage to the system board
or memory card. For memory voltage requirements, see Table 1.
To identify a 3.3-V 100-pin SDRAM DIMM, look for the part number label on the front of the card. (See
Figure 4.) Table 2 and Table 3 show the part numbers for the DIMMs.

Upgrading DRAM
Procedure for Cisco 2691
This section describes how to upgrade synchronous dynamic random access memory (SDRAM) dual
in-line memory modules (DIMMs) in Cisco 2691 routers.
The Cisco 2691 router contains two 168-pin DIMM sockets for SDRAM. Each socket can be filled with
a single 64-bit-wide, 168-pin SDRAM DIMM; however, if you install only one DIMM, you must install
it in slot 0.
You can configure SDRAM as a mixture of main memory, which is reserved for the CPU, and shared
memory, which is used for data transmitted or received by modules and WAN interface cards. See
Figure 7 for DIMM locations.
To see how much memory is currently installed in the router, enter the show version command while the
router is in privileged EXEC mode (Router#). Near the middle of the resulting output, a message similar
to the following appears:
cisco 2691 (R7000) processor (revision 0.5) with 121856K/9216K bytes of memory.
This line shows how much memory is installed (in this example, 121856 Kb / 9216 Kb). The first number
represents primary memory, and the second number represents shared memory. Your router supports up
to 256 MB of SDRAM.
Note
To use a 64-bit mode SDRAM configuration, the memory size of the DIMM in slot 1 must be less
than or equal to the memory size of the DIMM in slot 0.

Replacing the Internal Flash Memory SIMM
Step 3
Hold the DIMM with the polarization notch on the right, near the rear of the chassis, and with the
connector edge at the bottom.
Step 4
Beginning with socket 0, insert the DIMM perpendicular to the socket. Push firmly into place, as shown
in Step 1 of Figure 9. When the DIMM is properly seated, the socket guide posts fit through the
alignment holes, and the locking spring clips click into place, as shown in Step 2 of Figure 9.
Step 5
Ensure that each DIMM is straight (perpendicular to the socket). (See Figure 9.)
Caution
It is normal to feel some resistance when installing a DIMM, but do not use excessive force on the
DIMM, and do not touch the surface components.
Step 6
Repeat Step 3 through Step 5 for each DIMM.
Step 7
Reinstall the router cover. Follow the instructions in the “Closing the Chassis” section on page 19.
Replacing the Internal Flash Memory SIMM
The system code (router operating system software) is stored in a flash memory 80-pin single in-line
memory module (SIMM) in Cisco 261x, Cisco 262x, Cisco 265x, and Cisco 26xxXM routers.
Note
In Cisco 2691 routers, the internal flash memory is a compact flash card, not a SIMM. If you are
replacing the internal compact flash card in a Cisco 2691 router, refer to the Installing and Formatting
ICisco I2691, Cisco I3631 and Cisco I3700 Compact Flash Memory Cards document.
Tools Required
You need the following tools to remove and replace the system-code SIMM on the router:
•
Medium-size flat-blade screwdriver (1/4-inch [0.625 cm])
•
ESD-preventive wrist strap
•
Flash SIMM
Preparing to Install the Flash SIMM
There is one system-code (flash memory) SIMM socket on the system board. You can verify how much
flash memory is already installed in your router by entering the show flash EXEC command.
Caution
The system code is stored on the flash memory SIMM, but new system-code SIMMs are shipped
without preinstalled software. Before continuing with this procedure, use the copy flash tftp
command in privileged EXEC mode to back up the system code to a TFTP server.

Before testing your ROM installation, close the router chassis using the procedure provided in the
“Closing the Chassis” section on page 19.
Test your installation by rebooting the router. If you installed the ROM correctly, the router boots into
the ROM monitor or operating system.
If you suspect that the ROM is inserted incorrectly, remove and reinstall the ROM as described in the
“Replacing the Boot ROM in Cisco 2600 Series Routers” section on page 15. Reboot the router again.
Closing the Chassis
This section describes the procedure for closing the chassis.
Installing the Chassis Cover on Cisco 261x, Cisco 262x, Cisco 265x, and
Cisco 26xxXM
To close the chassis:
Step 1
Caution
Referring to Figure 1 and Figure 2, press the two chassis sections together and verify the following:
•
The top section fits into the rear of the bottom section. The bottom section fits into the front of the
top section.
•
Each side of the top and bottom sections fits together.
To fit the two sections together, it might be necessary to work them together at one end and then the
other, working back and forth; however, use care to prevent bending the chassis edges.
Step 2
When the two sections fit together snugly, slide the chassis top so it fits into the front bezel.
Step 3
Replace the cover screws. Tighten the screws to no more than 8 or 9 inch/pound of torque.
Step 4
Reinstall the chassis on the wall, rack, desktop, or table.
Step 5
Reconnect all cables. If the router uses a DC power supply, switch the circuit breaker to the ON position.
Installing the Chassis Cover on Cisco 2691
Step 1
Hold the cover so the tabs at the rear of the cover are aligned with the chassis.
Step 2
Push the cover toward the rear, making sure that the cover tabs fit under the chassis back panel, and the
back panel tabs fit under the cover.
Step 3
Slide the cover slightly to the left to lock the cover into position. (See part 1 in Figure 16.)

Opening a TAC Case
Using the online TAC Case Open Tool is the fastest way to open P3 and P4 cases. (P3 and P4 cases are
those in which your network is minimally impaired or for which you require product information.) After
you describe your situation, the TAC Case Open Tool automatically recommends resources for an
immediate solution. If your issue is not resolved using the recommended resources, your case will be
assigned to a Cisco TAC engineer. The online TAC Case Open Tool is located at this URL:

For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely
degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers
are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is “down” or there is a critical impact to your business operations. You
and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your
business operation are negatively affected by inadequate performance of Cisco products. You and Cisco
will commit full-time resources during normal business hours to resolve the situation.

Obtaining Additional Publications and Information
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.
